I've tried a lot of online dating sites and apps (Match, tinder, etc.)

My response rate is laughably low and I just don't get it. I'll usually write something like

"Hi I'm [my name]. How's your week/weekend/holiday going?"

Nothing 95% of the time.

Tinder and similar dating apps? If I get a match, I'll message hi and get nothing except the occasional scammer (who gets incredibly upset when I tell them I spent my money on candy when they need help).

Is it me? Is online dating really just shitty in general? I would like to meet someone this summer, so any help or just general info about online dating is appreciated, even if it's just "online dating is shit" so at least I know it's not just me.

TIA
